Cobalt Solutions, LLC announces the release of Cobalt V4.0, the latest version of their popular unstructured flow solver.

The major new advancement in Cobalt V4.0 is an Overset module featuring an automatic grid assembly process which determines hole-cutting, overlap regions, and interpolation weights to communicate flow field information between the separate grids.

Hybricon Inc. Senior Simulation Engineer Michael Palis was given the challenge by a defense contractor customer of cooling an ATR form-factor chassis that dissipates almost 200 watts and operates at altitudes up to 50,000 feet.

Palis used thermal simulation to evaluate a wide range of possible design configurations, focusing on heat sink design and fan performance at high altitudes. The simulation helped identify several alternative designs that would meet the customer’s demanding requirements. Based on Palis’ recommendations, the defense contractor built the system, which performed almost exactly as predicted by the simulation.

"The combination of Pro/ENGINEER for solid modeling and EFD.Pro for airflow analysis allows us to test our louvers for form, fit and function effortlessly," said Henry Aaldering, technical director at JAZO. "We can show the finished design to our customer complete with how it will look and work in just one day – that’s a saving of three weeks and thousands of Euros/dollars for each model."

CEEMO Engineering used EFD.Lab, an easy-to-use general purpose engineering fluid dynamics software from Flomerics Ltd., to test and optimize a new concept car. The entire design optimization process for the 2-seater chassis took about eight weeks despite the design engineer being a novice in the use of fluid analysis software.

“I am an aerospace engineer by background but I had never used CFD software so we did an exhaustive search to find the right tool for the design engineer,” said Evan van Wolfswinkel, an Engineer at CEEMO.

Best-known for its industry-leading EnSight software, CEI produces a full range of software applications for the scientific and engineering community covering all aspects of simulation, including meshing, plotting, process work flow, animation, and visualization.
